Kendall Jenner’s most out-there dieting trick isn’t a kale smoothie or a hip cycling class — it’s a paint color. The 21-year-old model recently revealed that she swears by the special pink wall inside her Los Angeles home, saying that looking at the particular shade suppresses one’s appetite while inducing a calming effect.

Jenner explained on her blog, KendallJ, that her pink room came to life after a recent dinner with friends who had just come from an exhibit in LA called “Human Condition.” One room at the exhibit was painted “Baker-Miller Pink,” with a placard saying that the color is “scientifically proven to calm you and suppress your appetite.”

There is evidence to support these claims. A study by scientist Alexander Schauss in the 1970s found that the color calmed some prisoners after they were exposed to it. And another study by Johns Hopkins researchers in the 1980s found that it reduced appetites in almost a third of 1,700 subjects.
